Why do techs keep swapping boards before checking the door switch
Had a guy bring in a Whirlpool dryer last week that two other shops quoted $280 in parts for, and it turned out to be a $12 door switch he never tested because he trusted the error code too much.
Watched a buddy chase the same ghost on a Maytag last month, swapped the control board and the door switch both before he finally stuck a meter on the old switch and found it was dead. Cost him a hundred bucks in parts he ate himself just because the code pointed at the board. Trust the meter, not the screen.
